Description

Technical Field

[0001] This utility model belongs to the technical field of fabric inspection machines, and relates to a fabric inspection machine with corrective properties. Background Technology

[0002] Fabric inspection machines are essential specialized equipment in the textile and apparel industry for inspecting extra-large, double-width, and single-width fabrics such as cotton, wool, silk, linen, and synthetic fibers. They play a crucial role in the production inspection of woven and dyed finished fabrics. Inspectors use these machines to promptly examine woven greige fabrics or dyed finished fabrics and address any issues found. This not only ensures the quality of the fabric meets the requirements of the final product but also allows for timely feedback of problems to each process stage, prompting improvements in processes to enhance product quality. However, this places high demands on the skills of the fabric inspection personnel.

[0003] Researchers have made many efforts to improve the performance of fabric inspection machines. For example, patent application CN219314143U discloses a fabric inspection machine with a correction mechanism. Although the correction device in this patent can better correct the deviation when rolling the fabric, the device is located above the fabric placed on the inspection table, which affects the user's observation of fabric defects. In addition, existing fabric inspection machines have other problems, such as the lack of safety protection for the fabric cutter, which can easily cause injury to the user.

[0004] Therefore, it is of great significance to study a fabric inspection machine that can correct deviations in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide a fabric inspection machine that can correct deviations.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fabric inspection machine with corrective properties includes a fabric inspection machine housing, a fabric inspection table, and a fabric cutter. The fabric inspection table is located on the top of the fabric inspection machine housing and is fixedly connected to the left and right sides of the housing. The fabric inspection table provides an area for the fabric to be unfolded, facilitating the inspection of fabric defects. The fabric cutter is used to cut the inspected fabric surface. The running path of the fabric cutter is parallel to the left and right direction of the fabric inspection machine housing. The fabric inspection machine also includes a far-infrared sensing device, a PLC controller, an alarm device, and a corrective device.

[0008] The far-infrared sensor is installed on the fabric cutter. The far-infrared sensor and the alarm device are respectively connected to the PLC controller. The far-infrared sensor is used to detect whether there is an obstacle higher than the fabric surface in the running path of the fabric cutter. If there is, it sends a signal to the PLC controller, which then sends a signal to the alarm device to sound an alarm and then stops cutting the fabric, thereby increasing the safety of using the fabric cutter.

[0009] The correction device is used to correct the deviation of the fabric; the correction device is located inside the fabric inspection machine housing.

[0010] As a preferred technical solution:

[0011] As described above, a fabric inspection machine with corrective properties includes a screw, bearing I, bearing II, handwheel, nut I, connecting plate II, sliding sleeve, long rod, and fabric roller.

[0012] The fabric inspection machine housing has a through hole on each of its left and right sides, denoted as through hole I and through hole II. Bearing I is installed in through hole I, and the outer ring of bearing I is fixedly connected to the inner wall of through hole I. Bearing II is installed in through hole II, and the outer ring of bearing II is fixedly connected to the inner wall of through hole II. The lead screw is placed horizontally and passes through the inner rings of bearing I and bearing II, passing through the left and right sides of the fabric inspection machine housing, and is fixedly connected to the inner rings of bearing I and bearing II. One end of the lead screw is fixedly connected to the handwheel.

[0013] The long rod passes through the left and right sides of the fabric inspection machine housing. The two ends of the long rod are threaded and are fixedly connected to the fabric inspection machine housing by a nut I. The fabric roller has a hollow cylindrical structure. There are two sliding sleeves. The fabric roller and the two sliding sleeves are all fitted on the long rod. The fabric roller is located between the two sliding sleeves. The sliding sleeves are used to limit the position of the fabric roller on the long rod.

[0014] There are two connecting plates II. One end of each connecting plate II is fixedly connected to a sliding sleeve, and the other end is fixedly connected to a lead screw nut. The two lead screw nuts are threaded with the lead screw.

[0015] If the fabric deviates during the operation of the fabric inspection machine, the fabric will be corrected by the correction device to keep the fabric in the center of the fabric inspection machine. Specifically, when the fabric passes the fabric roller on the correction device, the left and right movement of the two sliding sleeves is controlled by the screw, which indirectly controls the left and right displacement of the fabric roller.

[0016] As described above, a fabric inspection machine with corrective properties has a groove on the fabric cutter. A far-infrared sensor is slidably connected to the fabric cutter through the groove, and the groove is used to control the distance between the far-infrared sensor and the fabric surface.

[0017] As described above, the fabric inspection machine with corrective properties further includes a rotating roller I, a tension adjusting device I, a rotating roller II, a spreading roller, a rotating roller III, a tension adjusting device II, a rotating roller IV, a guide roller I, a guide roller II, and a guide roller III.

[0018] Tension adjusting device I and tension adjusting device II have the same structure; tension adjusting device I includes a tension adjusting roller, connecting plate I and a fixed roller; the two ends of the fixed roller are fixed to the left and right sides of the fabric inspection machine housing; there are two connecting plates I, referred to as connecting plate a and connecting plate b; one end of the tension adjusting roller is fixedly connected to one end of connecting plate a, the other end of connecting plate a is rotatably connected to the fixed roller, the other end of the tension adjusting roller is fixedly connected to one end of connecting plate b, and the other end of connecting plate b is rotatably connected to the fixed roller.

[0019] Tension adjustment device I is installed between rotating roller I and rotating roller II;

[0020] Rotating roller I, tension adjusting device I, rotating roller II, rotating roller III, tension adjusting device II, rotating roller IV, and guide roller I are located inside the fabric inspection machine housing; spreading roller, guide roller III, and guide roller II are located outside the fabric inspection machine housing, with guide roller III and guide roller II located on the front and rear sides of the fabric inspection table respectively, and guide roller II located between the fabric inspection table and the cutting knife.

[0021] Regarding tension adjustment, compared with the prior art, this utility model adds a tension adjustment device I, which can better adjust the tension and achieve the effect of no tension during fabric inspection.

[0022] As described above, the fabric inspection machine with corrective properties has a corrective device located inside the outer casing of the inspection machine and below the guide roller III. During the fabric conveying process, the fabric passes sequentially through the rotating roller I, the tension adjusting roller of the tension adjusting device I, the rotating roller II, the spreading roller, the rotating roller III, the tension adjusting roller of the tension adjusting device II, the rotating roller IV, the guide roller I, the fabric roller of the corrective device, the guide roller III, the inspection table, the guide roller II, and the cutting knife.

[0026] Precise Deviation Correction Function: The deviation correction device precisely controls the left and right displacement of the fabric rollers through mechanisms such as lead screws, nuts, and sliding sleeves, achieving precise deviation correction of the fabric. This function ensures that the fabric remains centered throughout the inspection process. The deviation correction device is located inside the fabric inspection machine casing, below guide roller III, ensuring unobstructed views of the fabric on the inspection table, facilitating user observation and recording of fabric defects, and improving the accuracy and efficiency of the inspection.

[0027] Dual tension adjustment device: This fabric inspection machine employs two tension adjustment devices, located at the beginning and middle stages of fabric conveying, respectively. This design allows for better adjustment and control of fabric tension, ensuring the fabric remains tension-free during inspection, reducing deformation and damage, and improving inspection quality.

[0028] Flexible far-infrared sensing device: The groove on the fabric cutter allows the far-infrared sensing device to slide and adjust as needed, thereby controlling its distance from the fabric surface. This design enables the far-infrared sensing device to adapt to fabrics of different thicknesses, enhancing the adaptability and flexibility of the fabric inspection machine.
